I've had my Flying Eyes for only a few days, so my comments are somewhat preliminary. Comfort is good, but have yet to wear them under hearing protection or headsets, which is my main reason for buying them. They are very lightweight, which is great, but does raise questions about their ruggedness and longevity. The small selection of styles, along with minuscule color choices is a big negative. Hopefully this will improve as the company grows.

I am a professional race car driver and I was looking for a comfortable and resistant frame to use it with my helmet and I finally found the Flying Eyes Otus that fits perfectly.
I loved it so much that I told my co-driver and another driver to buy iy and they did. They also loved it.

Otus

These fit better under a headset than any other glasses I’ve ever tried. Two complaints- the frames have a sharp edges on the nose bridge that digs into my nose and the magnetic clip on sunglasses do not have an anti reflective coating so when you put them on you see too much of your own face

I would have given this 5 stars, but alas I had to go with 4 simply because they tend to fall off my face if I bend over and sometimes they don’t like to sit square on my face. The overall fit is great but I think it’s due to the bendy nature of the frames that causes it to be able to bend side to side and not sit square all the time, as well as not hang on to my head when bending over.
